Nand string current
Witryna27 paź 2024 · It means that the stored values in other cells cannot affect the state of the NAND string. Now that the other cells are made temporarily irrelevant, we are able to specifically read the value of our target cell. Generally, we read a cell's state by … WitrynaThe NAND strings are connected vertically in a series, and the memory transistors change from floating-gate types to trapped charge types. The BiCS 3D NAND Flash architecture is described in Figure 4. The first element of the architecture is the control gate stack shown by the
